FLUID-OPERABLE LUBRICATOR AND FEEDER FOR ENGINES.

Application led July 13, 1925. Serial No. 43,249.

This invention relates to a torce feed lubricator and distributor for locomotives and stationary engines.

The chief object of the invention is to provide a positive supply ot' lubricant tno an engine of the 'stationary or locomotive type only when the moving ing under the influence ot fluid pressure that is doing work. i

The chief feature of the invention consists in the operation of a 'forced feed lubricator by constantly applied fluid pressure emeach supply line is a 'ployed in the prime mover and associating therewith a distributor of a novel character also operable by 'fluid pressure employed in the prime mover.' ln the latter instance the distributor is operable by the dierential diaphragm pressures, the larger diaphragm being associated with the lower pressure which is intermittently applied. y

' The full nature of the invention -will be understood from the accompanying drawings and the following description and claims: y

I 'In the drawings Fig. 1 is a front view of a locomotive showing the invention associated therewith, the several parts oil the piping being shown diagrammatically. Fig. 2 is a side elevational view of the same. Fig. 3 is a central sectional view through the distributor. Fig. et is a longitudinal section through the lubricator and taken on line Lit-'4e oi' Fig. 6. Fig. 5 is a similar view taken atright angles to the figure shown in Fig. 4l. Fig. (l is anend view olf the lubricator.

In the drawings 11 indicates a locomotive having a boiler 12, cylinders 13a and 13b and supply lines 14 and 111i).A Associated with distributor herein indicated respectively by the numerals 15 and l5.

`Each distributor is connected by a conduit 1G to the source ot high pressure steam, to wit, the conduit 14. A conduit- 17` is connected to the distributor at one end and to the engine cylinder supply at the other, thus subjecting the distributor lto intermittent pressure. A conduitlS is connected to the lubricator indicated generally by the numeral 19. Said conduit 18 constitutes a high pressure lubricant supply line and serves to supply oil from the lubricator to the distributor 15. A line 2O connects the distributor to the supply line connected to the cylinder and thus the lines 16 and 2O are connected through the distributor and form parts thereof are mova by-pass leading from and thence to the supply line 14: of the engine.

Reference will now be had to Fig. 3, wherein the details ot the distributor device are shown. The body portion indicated generally by the numeral 15 includes a pair ot transverse communicating channels 21 and 22. The channel 21 communicates at one end with conduit 1G and at the other end with the conduit 20. A bushing 23 has a tapered outlet or passage 24C discharging into said passage 21. The channel 22 receives a sleeve 25 which terminates at the end lopposite from the end communicating with the conduit 21 in a valve seat 26. A valve'27 is associated therewith and carries a stem 28 tor aligning the coilv spring 29 and abutting an adjustable stop 30. The valve 27 also is extended and carries aV body portion 31 that has a predetermined tit within i said sleeve 25. A channel 32 communicates with conduit 18 at one end and thus the lubricator and is supplied with lubricant under high pressure. The cap 33 carried by the distributor 15 includes a'valve chamber 34 and this valve chamber communicates with the conduit 21 when the valve 27 is removed from its seat 26 through the predetermined lit between the stem 31 and the sleeve 25.

The opposite end ot the body 15 includes a chamber 35 in which is secured a` diaphragm 36 retained in position by a retainer 37, in turn supporting another diaphragm 33, likewise retained in position within a chamber 3S). An adjustable stop 4() is provided tor the diaphragm 38 and a stop 41 `carried by the diaphragm 33 has engagement with diaphragm 36.

The operation ot' the distributor device is as follows Whenever steam is supplied to the engine cylinder, and preferably the front end, and this occurs intermittently, pressure is applied to chamber 39. Diaphragm 38 moves toward the left with abutment 41. This engages diaphragm 36 and moves the same to engage the end of the stem 31 and unseat the valve 27 trom its seat 26. This permits the lubricant supplied by line 18 to pass from the valve chamber 311 to the passage 21 under high pressure.

High pressure steam also is passed through and travel 'of' stein 3l in bushing E22 .and by the regulated opening of the valve, the latter' being adjusted through abutment 30. lVhen the steam pressure supplied to the chamber 39 is released by being exhausted to the atmosphere or passed into a low pressure 'c'yiine der or to .accessories as is the common practice, the diaphragm 36 becomes effective and returns diaphragm 88 to its original position. Said diaphragme are limited in theirtravel to the right by abutment 4l and the adjustable stop i0. At the saine time, the spring 29 has seated the valve 27 and the lubricant supply is discontinued. Upon failure of the steam supply it will be readily apparent that the spring yQ9 cuts ofi' thew lubricant supply` Thus the distributor is adapted to withhold the lubricant from the device atv such times as the movable parts are not-movable under fluid pressure. 1 Reference will now be. had to Figsvl to 6 inclusive, wherein the lubricator 19 is il lustrated in detail. Said lubricator is connected by the lines i8 to the distributor previously described. The. body portion contains a. chamber which rotatably supports aI shaft 5l which carries a wheel 52 provided with turbine vanes or blades 53 upon the ,periphery orlside thereof. A nozzle 54; isconvnected by theconduit 55 to the source ofhigh pressure steam, to-wit, the supply pipe or conduit ld. The steam, after engaging the blades and causing the turbine wheel to rotate, passes outwardly and exhausts through the port or passage 56. This is connected to` the exhaust pipe of the engine or the. same may be. connected to a. low pressure cylinder, atmosphere orto accessories as is the custom- `ary practice. The lubricator y housing includes a tubular channel 6l in which is mounted by press fitting, a sleeve 62, and concent-rically positionedand rotatable within the saine is another sleeve 63, Iboth sleeves being fianged and separated by a thrust bearing 64. Mounted within and secured to the sleeve 63 is a screw impeller 65 which is connected at one end tosha-ft 51 and is an eX- tension thereof, a. partition 57 and packing 58 separating the lubricant chamber from the turbine chamber. A supply port 60 leads from a suitable reservoir 59 carried by thelubricator vhousing 19 or secured thereto and discharges into a chamber66` It is to be understood that a. ball check 70 permits re turn flow of the lubricant from the passage 60 and chamber 66 to the reservoir 'for relier" of excessive pressure,'while a suitable ball check construction 67 prevents return flow of the high pressure. lubricant from the conduits 1S to the chamber 66 when the device is stat-ionarv,

Rotation of the. shaft 5l by the turbine wheel rotates the screw impeller 65 and sleeve 63,4 to convey oil from the chamber 66, supplied by reservoir 59 through the ball check when the turbine wheel is rotated.

ably4 the discharge end of the lubricator 1s 5 controlled passage 60, to thezhigh pressure conduit or conduits 18 controlled by the ball check 67. Thus lubricant is supplied only Preferprovi'ded with a =checlr controlled relief valve 76 communicating with the reservoir for discharging the surpflus lubricant to the. reservoir.

Fromthe foregoing' it will be noted that the lubricator and distributor devices 'are so arranged' that 4 the lhigh pressures are all contained with-ine'nclose'd oasings and the lubricator and distributor parts are what maybe termed directly connected together, thereby eliil'ninating the necessity of' stufling boxes and t-h'e like heretoforev required.
